When filling drywall panels, a so-called joint tape is often used for the joints. On the other hand there are craft businesses that advise against a joint tape and certain conditions. When to use a joint tape with Rigips and when not, you can refer to the following guide.
Rigips or plasterboard
First, a short note about "Rigips". Rigips panels are plasterboard or GK panels. Specifically, it is the brand name for plasterboard manufacturer Saint Gobain. Since this manufacturer was already on the market, as this form of drywall became more and more prevalent and market leader, the brand name Rigips became synonymous with the term gypsum board or GK board. So when we write about Rigips below, it means gypsum plasterboard in general terms.
The processing of plasterboards or plasterboard
Rigips panels can be used on walls in different ways:
- screwed to a stand as a separate partition wall
- glued to an existing wall
The joints of the Rigips panels are filled. For this purpose, a joint tape is often used. This is in principle a reinforcing strip, which is to make the grouted joint more resistant, for example, against cracks. Versp Fill plasterboard with or without joint tape?
However, it is becoming more and more common to hear that the connecting joints of Rigips could be filled even without a joint tape. Many DIY enthusiasts are therefore unsure. Basically, that's right. Previously, a filler was used to fill the Rigips joints. Today, on the other hand, usually two different fillers are used for pre-filling and post-filling.
In addition, the leveling compounds, like flex tile adhesives, can be specially tempered and then more flexible. In other words: these fillers do not tear so easily, if it should come to tensions or mechanical pressure. And so we would be at the point when a joint tape for Rigips is recommended and when you can do without it.
Use a joint tape for the Rigips panels if there is a high probability of cracking
So it has something to do with the probability of cracks along the joints. Stress cracks, for example, occur at butt joints when two different materials collide at the same time, as they also have a different thermal expansion. So, for example, when connecting joints to other materials you should use a joint tape. Trocken Dry wallboard glued to an existing wall hardly moves at all, unlike a dry wallboard attached to a stud. However, if it becomes a complete drywall, the more unstable it becomes. Especially if it can not be screwed to the floor and can only be attached to the side connecting walls.
Are you unsure, better always use a joint tape
Basically, a pure drywall is therefore "less stable" than glued plasterboard on a wall. By design, this instability can be greater. Therefore, it makes sense here to use a joint tape.
From which size and type of installation, it is not possible to say blanket. Rather, you should not give up a joint tape, if you are not sure that the grouted joint could not tear later. On the other hand, in the case of glued plasterboard you can do without a joint tape in most cases.
